MINING-MACHINE.

Application filed May 28, 1904, Serial No. 210.174.

To all whom it may concern.-

Be it known that I, Emuuxn U. Honors, a citizen of the United States, residing at New York, in the county of Queens and State of New York, have invented a new and useful Improvement in hinting-Machines,of which the following is a specification.

This invention relates to mining machines.

The object of the invention is toprovide a mining machine, and especially a mining machine of the type known as pick milling machines, which is simple in construction and etlicient in operation.

A further object of the invention is to provide an improved n'iining machine wherein the mining tool is, under the control of an operator, advanced to its work and is op'- erated to effect the mining operation.

matically removed, and power mechanisms for controlling the movements of the tool, and the operation of the removing mechanism is readily controllable by a single attendant on the machine.

Other objects of the invention will appear mor'. fully hereinafter.

The invention consists substantially the construction, combination, location and arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

, Referring to the accompanying drawings, and to the various views and reference-signs appearing thereon,

Figure l is a view in verti ral longitudinal section of a mining machine embodying the principles of my invention, the plane of section being indicated by reference line 1-1, Fig. 2, looking in the direction of the arrows.

Fig. 2 is a view in rear elevation of a mining machine embodying the principles of my invention, the delivery belt for the material mined being shown in vertical transverse Section. i

Fig. 3 is a top plan view of the same, parts broken out and parts in horizontal section.

Fig. 4 is a view in front elevation, parts broken out and parts in vtrtieal transverse section, on the line -l-l of Fig. 1, looking in the direction of the arrows.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In the construction and operation of llllll-l mining operation throughout the entire transverse area of such wall, and to this end it is desirable to provide means for operating the mining tool andalso for so shifting or moving the tool that it will not only be operated, but Will be moved both horizoutally and vertically, and also will be ad vanced as the 'mi ing operation proceeds.

It is also desiriijble to provide means for eiliciently advancing the frame upon which the tool is mounted as the mining operation proceeds, and to anchor the same in advanced position and against recoil due to the delivery of the blow of the tool while efl'ccting the mining operation.

It is also desirable in machines of this class and so as to avoid interruption of the mining operation to provide means which are simple and ellicicnt for removing the mined material as the mining operation proceeds, thereby enabling the machine to be continuously operating without interruption .for the purpose of removing the mined material.

It is also desirable that the various mech anisms for accomplishing the objects and operations above stated he cfiiciently controlled by the machine operator.

It is among the special purposes of my present invention to provide a construction of pick or similar mining machine. wherein the desirable objects above stated are accomplished and in a most ellicient manner.

In the accompanying drawings I have shown a construction and arrangement of mechanism efiibodying the principles of my invention, and which embodies the best form in which I at present contemplate carrying the invention into practical operation, but which is capable of modification and change in the various details of construction and arrangement of the parts thereof, without departure from the spirit and scope of my invention. While, therefore, I have shown and will now describe the specific construction and arrangement of one embodiment of my invention, I do not desire to be limited or restricted thereto.

In the drawings, reference-sign A dcsig nates the frame-work of the machine, upon which 'the various operating parts are mounted. Upon the side-pieces of the main frame A are mounted guides B, adapted to receive av sliding frame C. Pivotally connccted to the sliding frame C is a tool frame D,jthe pivotal connection of the tool frame to the sliding frame being in the form of a vertically arranged stud E, shown in full lines ln-Fig. l, and in dotted lines in Fig. 3, said stud forming a vertical axis about which the tool frame D may swing horizontally. The tool support is indicated by ref erence sign F, and is'pivotally connected by means of a horizontally arranged stud G, upon the tool frame D, whereby the tool support may be rocked or swung in a vertical plane. The particular form of mining tool selected for the purposes of illustration is an ordinary style of pick ll, and is suilably mounted in the tool support 1* for ope'ation. This tool may be operated by any suitable or convenient motor. In the l'ol'm shown, to which. however, my invention is not to be limited or restricted, I form the tool support into a cylinder J, in which operates a piston K, the stem of the pick oi; other tool being connected to the piston. L designates a supply pipe for supplying an operating medium to the machinm such. for instance as compressed air. (ounnuuicatiug with supply-pipe L is a delivery pipe M, and which may be ctmtrollcd in its connection with the supply pipe in any convcilieut manner, as, for instance, by means of a hand-valve N. (see Figs. 1 and The delivery pipe M dclivers into a valve chest 0, in which is arranged to operate a valve P, for controlling the supply of the operating medium to opposite ends of the cylinder J. The valve 1 may be operated automatically in any convenient manner, as, for instance, by means of a valve rod or stem-Q, having its ends projecting through the casing of the valve chamber and in the path of the ends of rocker levers R, R )ivotally mounted upon the casing of cylin or J, the opposite arms of said rocker levers being arranged in the path of pins S, arranged on opposite sides of and adapted to be alternately engaged by the piston K in the reciprocating movements thereof, said pins operating through openings or boxes formed through the walls of cylinder J, so that when the piston K approaches one limit of its rcciproca-.

tory movement it will engage one of the pins S and project the same outwardly through the cylinder casing and against one arm of its associated rocker lever B, thereby rocking said lever and causing the other arm thereof to engage valve stem Q, and project the same in the opposite direction to shift the valve into position to admit the operating fluid to the opposite side of the piston, and when the piston K approaches the opposite limit of its reciprocatory movement within cylinder J,'said piston engages the other pin S, thereby projecting the same through the cylinder casing and effecting a rocking movement of rocking lever R on the opposite side or end of the cylinder, thereby shifting the valve P back in the opposite direction to that above described, and in each movement of the valve P, one end or the other, as the case may be, of the tool operating cylinder .T is opened to exhaust. As the parts are shownin Fig. 1, the right-hand end of the cylinder J is opened to receive a supply of the operating medium preparatory to projecting the tool unlock I I while the opposite or lefthand end of cylinder J shown open to exhaust, the exhaust connection bein indicated at T. In this manner the tool is continuously operated, and may be arrested or started by suitable manipulation of valve N.

As above stated, I do not desire to be limited or restricted to the particular form of motor employed for actuating the pick or other tool, as it is obvious that the same may be operated by steam or hydraulically, or by .any other suitable or convenient form of motor.

That shown, however, I consider most practical and eflicient.

I will now describe means for advanc ing the sliding frame C upon the main frame A.

Reference sign A designates a cylinder, the casing of which is rigidly mounted and connected to or formed with the sliding frame C. In this cylinder is arranged a piston B, the rod or stem C of which is rigidly bolted or connected, as, for instance,

at D, to the main frame of the machine,

or to a cross-bar E thereof. By admitting an operating medium to cylinder A on one side or the other of piston B, said piston being held stationary, the cylinder A is used to move longitudinally, and since aid cylinder is rigidly connected to or is ormed with the sliding frame C, it is ob {ions that said sliding frame and the parts upported thereby will partake of the longitudlnal movement of cylinder A. While I have shown a .cylindcr and piston motor for effecting the liding movements of sliding frame C, I d not desire to be limited or restricted thereto, as any suitable or convenient form of motor for efi'ecting the desired result may be employed. The form of motor shown, however, is practicable and efficient. In the particular form of motor shown any desired operating medium whether liquid or fluid may be employed. In practice, however, I prefer to employ a liquid, as, for instance, water, for reasons which will be explained hereinafter. The supply and exhaust of operating medium to and from cylinder A may be controlled in any convenient manner, as, for instance, by means of a valve F. Where the operating medium employed in cylinder A is water or other fluid '1 provide 'a reservoir G, (see Fig. 1,) to receive the operating medium. From this reservoir the water or other fluid is drawn from said reservoir by means of a pump piston H, operating in a cylinder J through suitable 'valve' controlled openings or pas sages K, L, the fluid being delivered from cylinder J into a chamber M, through valve controlled ports N, the operation being that when the pum piston H is moved in one direction, say rom the left toward the right, as seen in Fig. 1, the operating fluid is drawn from reservoir G through port K, into cylinder J, while any operat= ing fluid contained in cylinder J on the opposite side of iston H is expelled or delivered from cylinder J through the port N at the right-hand end of cylinder J, and into the chamber or passage M; and similarly'whcn the piston H is moved in the opposite direction,tha.t is, from the ri ht-hand end of cylinder J, toward the le t-hand end thcreof,operating fluid is drawn into the cylinder J from reservoir G, through port L, while the operating fluid previously drawn into the left-hand end of cylinder J is expelled or delivered therefrom through the valve controlled port N, at the left-hand end of cylinder J, and into the chamber or passage M. A passage O delivers from chamber M to cylinder A, said passage being controlled by a valve F. An exhaust passage 1, Q. dclivers from cylinder A to reservoir G, and is also controlled by valve F. The parts are shown in Fig. 1 with the valve F opening communication between the left-hand end of cylinder A and chamber M to admit the operating medium to cylinder A at that end thereof, while the right-hand end of cylinder A is shown open to exhaust. By suitably manipulating the valve F, however, the chamber M and passage 0 ma be thrown into communication with the righthand end of cylinder A, and simultaneously the left-hand end of said cylinder is opened to exhaust at reservoir G.

The pump piston H may be operated in any suitable or convenient manner, and automatically, or by any suitable arrangement of motor. I'have shown a simple construction of motor for accomplishing this operation, and comprisin a cylinder R, in which operates a piston i an operating medium being introduced in cylinder R, and alternately on opposite sides of piston .S, in any suitable manner, as, for instance, by means of a valve T, having a stem A and operated by means of tumbler levers B and pins C in identically the same manner as that above describcd with reference to the motor for operating the pick or tool H, said valve operating to control the supply and exhaust of an operating medium to cylinder R. The particular operating medium is un important and may be either fluid such as air or a liquid suchas water. I have shown, however, a pipe connection I)", communicating with the compressed air supply pipe L, and delivering into the chamber of valve T. This pipe I) is provided with a hand operated valve E by which the supply of operating medium to operate the pump actuating piston S may be turned on or off as desired.

If desired, the fluidfin chamber M, and which is admitted to cylinder A under the control of valve F, may be maintained under any desired degree of pressure. To

this end I may employ any suitable or ordinary form of compressor. I have shown a simple form of compressor or accumulator, comprising a piston F operating within a cylinder G", and provided with a plunger ll" and operating in a cylindrical bore J, which communicates with chamber M. The piston ll forms a partition within cylinder (i and a suitable compressor medium is admitted to cylinder (i above piston F This may be accomplished in any convenient manner, as, for instance, by means of a pipe or other connection K, from main supply pipe L, and in which may be located a hand valve L for controlling the supply of pressure medium from main supply pipe-L through pipe K into the upper end of cylinder G above piston F. The lower end surface of plunger ll is exposed to the pressure of the operating medium in chamber M, while the upper surface of piston F is exposed to the pressure of the pressure medium admitted to the upper end of cylinder G By suitably regulating the pressure'thus supplied to the upper end of cylinder G it is obvious that the medium delivered by the pump piston ll into chamber M may be maintained in said chamber M at any desired degree of pressure. As above indicated, however, the particular form or construction of compressor or accumulator is unimportant, as many specifically *diticrent forms may be employed without departure from the spirit and scope of my invention in this respect.

I have above stated that I prefer to em- )lo water as the o el'atin" medium for c 1- inder A but air may be used if desired. The reason for water as a preferable operating medium at this point is that by reason, of its characteristic of non-compressibilitycit may be employed by suitably manipulating valve F as an operating medium to cause the cylinder A to travel or move longitudinally upon its piston B and to advance the slide frame 0. When the desired extent of advancement of said frame has been effected, by simply cutting off the supply and exhaust of the water to and from cylinder A, the body of water remaining within the cylinder A and on opposite sides of piston B, forms, in effect, a lock to hold the sliding frame C in the position thereof to which it has been advanced or removed.

I have above indicated that the frame D is pivotally connected to sliding frame 0 upon a vertical pivotstud E, so tluit said frame D may be rocked or swung horizontally in the operation of the machine. I have also explained that the tool support F was pivotally connected upon a horizontal axis or pivot stud G to the tool frame D, so

that the tool support carrying the tool may be rocked or swung vertically to effect the mining operation. It is important that the horizontal and vertical swinging movements of the mining tool thus permitted be effected independently of each other, so as to enable the tool to command the entire transverse face or surface of the wall to be mined, and in accordance with the principles of my intention I propose to provide power actuated means and independent of each other and under the ready control of an attendant for efl'ecting the rocking or swinging movements referred to. In Fig. 1 I have shown in detail the power actuated mechanism for rocking or swinging the cutter support F about its horizontal pivot stud or axis G. Of course, it is obvious that any suitable or convenient form or construction of motor for accomplishing this result, and which may be arranged under the control of the machine attendant, may be employed for this purpose. While, therefore, I have shown and will now describe one form of construction for accomplishing the desired object, I do not desire to be limited or restricted to the particular construction shown.

M designates a cylinder, which is mounted upon, carried by or formed with the tool frame D to rock or swing therewith. \Vithin cylinder M is a piston N", the rod or stem (7) of which is connected to a cross-head P, to which is pivotally connected one end of a link Q the other end of said link being pivotally connected to a crank arm R", connected to pivot stud G. From this description it will be seen that when the piston N is shifted in one direction or the other pivot stud G is rotatively actuated in one directionor the other, according to the direction of movement of the piston N. This pivot stud is splined in its bearing seat in the tool support F, so as to secure coincident rocking or swinging movement of the tool frame. Operating medium may be supplied to cylinder M for actuating piston N in any suitable or convenient manner. Although compressed air may be used if desired, in practice I prefer to employ hydraulic power in this connection, for the reason that thereby I am enabled to lock the piston N in any desired position in a manner similar to that above described with reference to the looking of cylinder A, and by locking piston N in any desired position against movement it is obvious that the tool support F will be held in any desired position of vertical inclination. Where water is employed as the pperating medium I provide a pipe S leading from and communicating at one end with chamber M into a casing T in which casing is arranged a passage, controlled by a valve A. Pipes B 0 lead from the valve chamber or the passage controlled by valve A, into the respective ends of cylinder also com unicates M. An exhaust pipe D with the passage which valve A controls,

said exhaust pipe delivering through pipe connections E Q, into reservoir G.

It should be observed that the pick machine comprising the pick and the means for operating the same percussively is mounted on a platform which reciprocatcs on the main rame so as to render the ick machine adjustable longitudinally. he pick itself is mounted for vertical movement by being pivoted to a carrier which supports the motor for swinging the pick n a vertical plane, The carrier itself is pivoted to the supplemental frame which supports a motor for swinging the carrier laterally together with the pick. This arrangement secures universal movement of the pick withm the area over which it is intended to operate. The pick, therefore, commands the entire area of the mine heading. It should be observed that inasmuch as the common source of supply L may be compressed air the motors for swinging the pick vertically and laterally may be operated by compressed air, in which event the pick or punchcr will be operated by yielding means to swing the same laterallv and vertically. It is evident that if the ick strikes a glancing blow on the face of t 9 coal or other material the air in the motor c linder M will permit the piston N to held. In the same manner the air in the cy inder F. as shown in Fig. 3, will ermit the piston G: to yield against the alr within said cylinder.

From the foregoing descri vtion it will be seen that by suitably manipu ating valve A, the operating medium will be delivered from chamber M, through pipe S, and nssage of'casing T, and valve A, into eit er one or the other of pipes B, C", according to .the position of valve A, the other of said pipes B, C being at the same time opened to exhaust through pipes D, E and Q. to reservoir G.

If desired and as shown, I may employ a similar arrangement for imparting the horizontal movements a; the tool frame I) on its vertical pivot stud E, as above cxlained, and which frame carries the cylmder M The particular form of power actuated device or motor for accomplishing this result is unimportant. In Fig. 3 I have shown a construction. for accomplishing the desired result, comprising. a cylinder F in which operates a piston G", to the rod or stem H of which is connected a crosshead J, one end of a link K being pivotallv connected to the crosshead J, the other end of said link being pivotully connected to a crank nrm ll". conncctcd to rock with pivot stud E, said pivot stud being suitably splincd or otherwise connected to the tool frame D to rock therewith, the parts shown and as abol'e referred to for effecting the horizontal 'ocking movemcnt of the tool frame D being substantially identical. in every particular with the similar parts above referred to for effecting the vertical rocking or swinging movements. The operating medium, whether fluid such as compressed air or a liquid such as water, may be supplied to and exhausted from cylinder F or otherwise controlled in any suitable or convenient manner, as, for instance, by

means of a valve M, arranged to control the supply and exhaust ports similar in all respects to the arrangement and operation of valve A above described. By employing water as the operating medium I secure the advanta es of a lock for holding piston G in any desired position as above explained with reference to piston N 2 and cylinder A.

It is desirable, as above stated, to provide means for advancing the main frame A through the room or entry as the mining operation proceeds. It is also desirable to provide means for efficiently looking or anchoring the main frame in its adjusted positions. These results may be accomplished in many specifically different ways. I have shown simple and efficient means for accomplishing the result. wherein I employ anchor devices in the form of rods N, and which at their outer or free ends are arranged to engage the walls of the room or entry through which the machine is to be progressed. It is obvious that as many of these anchor rods may be employed as may be desired. I have shown three of such devices, one engaging the roof of the entry or room and one engaging each of the side walls thereof. but I do not desire to be him itcd or restricted in this respect. These rods form piston rods for pistons f)", (sec Fig. 1,) said pistons operating in cylindcrs P hinged or pivotally mounted, as at Q. upon the main frame A of the machinc. and extending rearwardly and preferably in an outwardly inclined position, as clearly shown in the drawings. If desired, the cylinders P may be yieldingly pressed or swung outwardly so that the outer free ends of rods )1 will normally engage or bear against the surface of the wall or sides of the room or entry. To this end I provide a spring R suitably connected at one. end to a fixed part'of the framework of, the machine and at the other end to a tail-piece or extension S, of cylinders P", said tailpieces projecting beyond the points of pivotal connection Q, of the cylinders upon the main frame. An operating medium may be admitted to the respective ends of one: cylinder P in any convenient manner, so as to cause a relative longitudinal movement of pistons O and cylinders I. In order to effect the advancing movement of the main frame the outer ends of the rods N anchor or bear against the walls or ceiling of the room or entry, and by admitting operating medium to the cylinders P on opposite sides of the pistons 0, it will be seen that the main frame carrying the cylinders I. will be advanced or pushed forwardly, and by admitting operating medium to the other or outer ends of the cylinders the pistons 0 will be moved into the cylinders. thereby drawing the arms N into the cylinders to enable the outer of the free ends thereof to gain a new engaging or anchoring place. In this manner the main frame may be advanced along the entry or room as it is made by the operation of the minin tool H. As aboveindicated, however, the anchoring and ad 'ancing devices may be power actuated by any other suitable form of motor. That shown, however, I deem simple and etlicients Vhere a pressure medium is employed as the operating medium I prefer to employ water, as thereby the operating medium forms a lock when both the su ply and exhaust thereof is cut off from the cylinders P. so as to lock or hold the anchoring devices and hence the main frame in a position advanced or whatever position to which it may be advanced. Where water is employed as the operating medium, such medium may be supplied from chamber M in any convenient manner, as. for instance, through a pipe A", delivering from chamber \"l' into a passage or chamber of casing T, and which is controlled by a valve ll. An exhaust pipe connection delivers from said passage into exhaust pipe 15"". and thence through exhaust passage Q into reservoir G. Also con'nnunicating with the passage which is controlled by valve It", are a syst em of pipes I), leading to corrcspoiuling ends of all of the cylinders P, and also a system of pipes E leading to opposite ends of all of the cylinders l. 'lherefore, by suitably manipulating valve It all of the cylinders P may be simnltmn-mlsly opened to the source of supply of the operating medium at the same relative ends thereof, while at the same time the' opposite ends of all of Said cylinders are opened to exhaust. As the parts are shown in Fig. 1, the valve B is in position to open the outer ends of all of the. cylinders l to exhaust and the inner ends thereof to the source of supply of the operating medium.

In practice I iroposc to mount the pump cylinder J and its actuating pump cylindcl' R, the compressor cylinder G and casing T and the parts associated therewith. upon the'sliding frame (I; and consequently the pipe connections to the various operating cylinders. except cylinders A and I should be flexible connections to permit of the relative movements of the parts actuated thereby. This is unnecessary, however, so far as cylinders A and I are conthe main frame.

cerned, because said cylinders are mounted upon or formed to move with the sliding frame C.

As the mining operation progresses, the coal or other material detached by the oper ation of the tool would fall to the floor of the entry or room and there form an obstruction to prevent the advancement of the frame of the machine. It is necessary, therefore, to provide means for etliciently removing the detached or mined material. Many specifically different constructions may be employed for accomplishing this re sult. IVhile, tl'leret'ore, I have shown and will now describe one form which I have found etiicient, I desire it to be understood that my invention is not to be limited or restricted to the specific construction shown. In the form shown I employ a scoop or shovel F, and provide the same with arms (i which arms are mounted upon to turn with a transverse shaft H, suitably journaled in aslide frame J" which latter is adapted to move in the guides J. Any suitable form of motor may be employed for advancing the scoop or shovel F, or retract the same. In practice, said scoop or shovel is arranged to move along or just above the surface of the floor of the room or entry in which the machine is working and at a point beneath said f ame. as clearly shown in Figs. 1 and 4, but by advancing frame J upon the main frame through the guides J the scoop or shovel F may be advanced so as to scoop up any detached or accmnulated coal or other material mined by the tool. and so as to be advanced clear of the machine frame. In the particular form shown I employ a motor cylinder K, upon the slide frame J, in which cylinder is arranged to operate a piston I the rod M of which is fixed to In this respect the motor is substantially the same in construction and operation as the cylinder A, the cylinder being movable and the piston fixed, and by supplying operating medium on one side or the other of the piston I! the slide frame J may be shifted or moved in one direction or the other, as the case may be. An operating medium may be supplied to the cylinder K in any convenient manner, as for instance, through supply pipes NE 0, from a passage controlled by a valve I, with which passage communicates or to which delivers main supply pipe It. \Vhile in the position in which the parts are shown in Fig. 1, both the supply and exhaust are cut off by valve 1 from cylinder K, but by shifting valve 1" in one direction or the other, either of the pipes N or may be brought into communication with the source of pressure main tained in pipe L, and the other of said pipes N", 0, opened to exhaust through the exhaust passage R. In practice, I prefer to employ a cylinder K on each side of the as indicated somewhat diagrammatically in Fig. 4. In such event, the cylinder K on one side of the machine is arranged to communicate with the cylinder on the opposite side of the machine through suitable pipe connections, as indicated at S, shown in both full and dotted lines in Fig. 5. so as to simultaneously admit or exhaust the operating medium to or from said cylinders. \Vhen the shoe or shovel F has been advanced underneath the pile of coal or other material mined the entire shovel is raised or rocked about the axis of stud H. so as to elevate or raise the shoe F, carrying the end thereof in front of and shield or guard A, until it is brought into inclined position to discharge the load car ried thereby on the belt or carrier M The vertical rocking movement imparted to the shovel or shoe F for effected by any suitably arranged power actuating mechanism, as, for instance, by means of a piston, indicated in dotted lines at T, Fig. 1, arranged to operate in a cylinder A, the piston rod B being connected to a cross-head C, to which is pivotally connected one end of a link l). the other end of said link being pivotally connected to a crank arm ll. attached to shaft H. In practice. I prefer lo employ two eylimlers A. one on each side of the machine. as shown in Fig. 5. each provided with a piston T. a cross-hezul, and a link I)", so that the shaft ll may be -l'0('l ('(l from both ends thereof. Any other suitable form of motor may be employed for ctl'ecting the rocking movement of the shovel F. \Vhere a piston and cylinder construction is employed I deliver an operating medium to opposite ends of said cylinder in any convenient manner, as. for instance, through pipes I (1", said pipes delivering to a passage arranged to he controlled by a valve H, and with which pas sage communicates the main pressure medium supply pipe I}, as, for instance, through passage J", said passage also exhausting through port; or passage K. In the arrangement of these parts as shown the pipe F" is open to exhaust, while-the pipe G 18 open to the source of pressure medium. By suitably manipulating valve H, the supply or exhaust to and from the cylinder A may he readily controlled. Indpractice, the cylinders A are arranged imme iately above the cylinders K", and are suitably connected together by pipes, indicated at L, whereby both the pistons T of both cylinders may be simultaneously operated by the manipulation of a single control valve H". By employing two motors, one on each side of the machine and each connected through links I) to the cranks E, the shaft H is eliiciently rocked to rock or swing the shovel F vertically.

By elevating the shovel F, the load of machine,

over thev this purpose may be object, but to which I do not desire to be wherein I employ The limited or restricted, and travelin belts or conveyers M, N. carrier 5 main frame 0 the machine, the roller P being located at the front end of the main frame, and the roller 0 in the rear part of the main frame and in a somewhat higher plane than roller P, so as to give the carrier a vertical inclination rearwardly. The carrier N operates over a. roller Q suitably journaled in the main frame and extends rearwardly and upwardly therefrom to a convenient point of delivery into a car or other receptacle. The carriers M N may be driven in any convenient manner. I have shown a simple arr-an ement, wherein the shafts of rollers O", a, have spur gears R; S, mounted thereon, with both of which engages an intermediate spur gear T mounted upon a shaft A, extending transversely of the machine, and to which rotary motion may be imparted in any suitable or convenient manner, as, for instance, by means of a motor B. The particular form of motor employed for this purpose is unimportant. I have shown a compressed air motor in the form of a cylinder, the pitman rod C of which is connected to a wrist pin D, on a disk E, mountedon shaft A. The operating medium may be supplied to the cylinder B to operate a piston therein in any convenient manner, as, for instance, through a supply pipe F, (see Fig. 1,) which communicates at one end with the fluid pressure supply pipe L, and at the other end delivers into a valve chest G, in which may be arranged a valve similar in all respects to the valve P or the valve T, by which the sup ly of operating medium to the respective en of the cylinder and to exhaust may be controlled in the ordinary manner. A handvalve H, in pipe connection F, may serve to out 01f or turn on the pressure medium between main supply pipe L and the pi e connection F Through t e rotation of shaft A a travel imparted to the carrier belts M, N The y is material deposited upon the carrier M shovel F is delivered from said carrier upon.

is mounted upon rollers O P, suitably journaled in the sometimes pendent of each other and suitable or conveniently arranged car or receptacle.

In operation, an attendant occupying a position upon sliding frame C, is enabled to readily control the several valves above referred to, and through which the various mechanisms described are operated. It will be observed that in operation the main frame is advanced along the room or entry as the same is formed through the mining operation, said main frame being forced for- \vardly by the anchor rods when the latter are suitably actuated, and is locked or anchored in advanced position to take the recoil or shock resulting from the delivery of the blow of the mining tool. It will also be observed that the tool is supported and mounted so as to be capable of swinging in both horizontal and vertical planes without interruption of the continuous reciprocatory movementsthereot',themechanismsemployed for efi'ccting the vertical and horizontal swinging movements of the tool being indeunder the efficient control of the operator. It will also be observed that by supporting the mining tool upon a frame mounted to slide in the main frame, such tool may be advanced to its work upon the main frame, the latter remaining anchored and stationary until the tool has sufiiciently completed its work within the area commanded thereby to permit the main frame to be again advanced. It will also be observed that although compressed air may be used by employing hydraulic means for advancing the sliding frame which carries the mining tool and also for operating the mechanism for imparting the swinging.

movements to the mining cutter, I am enabled to hydraulically lock the parts whenevc: desired, thereby forming, in effect, an anchor for resisting or taking up the shock due to the delivery of the blow of the mining tool, and hence rigidly holding the parts in the positions to which they have been actuated by the hydraulic mechanism. It will also be seen that by partially withdrawing the scoop or shovel F underneath the main frame said main frame is enabled to be advanced closely up to the (point of application of the mining tool, an thereafter as the mining operation proceeds theushovel may be advanced from beneath the main frame and underneath the pile of accumulated material mined or detached by the mining tool, and then elevated or raised so as to transfer the mined material to the carriers, by which such material is delivered to a point in the rear of the machine, enabling the same to be readily and uickly removed from the room or entry an without, interruption of the continuous operation of the machine.

, In transporting the machine to and from the place where it is required fo use, it may be desirable to detach the supplcmental delivery carrier N or to remove the same from danger of accident, or from position forming an obstruction to the ready access to the machine. To accomplish this result, I provide the main frame with trackways A" (see Figs. 1, 2. land 5), in which are received the ends of the shaft ll", over which supplemental carrier N operates. By this construction it will be readily seen that when the auxiliary delivery carrier N is not required, the shaft 15*, on which gear S is mounted, is shifted or moved so as to detach said gear S from engagement with its drive gear'T and said shaft is then shifted or moved with the ends thereof traveling along the guides A", thereby enabling the auxiliary carrier N to be housed within the main frame of the machine.

It. is believed that the construction, func tion and mode of operation of the various devices above described will be readily and fully understood from the foregoing description, when taken in connection with the accompanying drawin s.

Obviously those skille in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of my invention as defined by .the claims hereto appended. I desire, therefore, not to be restricted to the precise construction disclosed nor to an particular operating medium for the vanous motors. While the term mining tool is intended to be construed broadly, I Wish the term pick machine wherever used in the claims to be understood as of that type wherein the pick is operated percussively or by quick, repeated blows.
